IMCPROVED ORE-WASHER AND SEPARATOR.

The Scedtlerreferred to in these Letters Patent and making part of thelame.

vTo all whom it ma/y conce/rn:

Be it known that I, J ULIo H. RAE, of Syracuse, in the county ofOnondaga, State of New York, have invented a new and improved Ore-Washer and Separator; and I do hereby declare the following to be afull, clear, and exact description thereof', which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specification, in whichdrawingi Figure 1 represents a longitudinal vertical section of thisinvention. 7

Figure 2 is a sectional plan@ or top view thereof.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of' one or more separators,each separator being placed into a shallow pan, and provided withaperforated hollow globe or rose, which connects with a pipe containingwater, under pressure, in such a manner that, by admitting theV pulpinto the separator, the light parts are separated from the heavierparts, and driven up, and caused to low over the edge oi" the separatorinto the pan, while the heavy parts y,settle down and collect on thebottom of the separator, abd, by these means, for instance, thequicksilver generally used in treating auriferous orcs can be readilyseparated from the pulp with which the same is mixedV The letter Arepresents a tank, which serves to receive the pulp, such as thetailings, fiowing from an amalgamator, or, if desired, a pulp composedof' ground ore and water.

In this vessel, the pulp is agitated by a series of beaters B, Whichextend from a vertical shaft, C, and it is allowed to discharge fromvsaid vessel through a spout, a, into a Washer or separator, D.

This separator is placed in a pan, E, and it is provided With aperforated hollow globe or rose, F, which connects with a pipe, G,containing water under pressure. p

When the pulp begins to flow into the separator, Water is admitted intothe perforated globe, and the jets of Water issuing from thepelforations of' said globe meet the current of the pulp, and serve toseparate the lighter from the heavier parts, so that those parts of thepulp which have the greatest specific gravity ,will

precipitate to the bottom of the separator, while the light parts arecaused to How ofi, over the edge thereof, and collect in the pan E.

From this pan extends a spout, el. over a second separator, H, in whichthe pulp escaping from said pan is exposed to anotherseparating-operation, and so on until the separation of the variousparts of the pulp has been carried on to the desired degree.

By these means, I am enabled to separate and save from the tailings ofan anialgainator a large percentage of quicksilver, which is no\T lost,and the expense of the ainalgamatiugprocess is materially reduced.

My apparatus can, however, also 4be used with advantage for separatingthe precious metals from the ores containing the saine, or, in fact, forseparating bodies of difierent speciiic gravity.

Having thus described my invention,

What I claim as new, and desie to secure by Letters Patent, is-

'lhe arrangement of one or more separators D, each placed in a pan, E,and provided with a perforated hollow globe or rose, F, which issupplied with Water under pressure, substantially in the manner and forthe purpose set forth.
